Ebon Blade

so umm about that cinematic… haven’t been back to bfa in a minute. I watched it and i was shocked as hell. My question is what the hell is the ebon blade gonna do now? Considering the scourge will return… will they have to work hard as hell to rout them back to northrend or the plaguelands? I’m still trying to figure out the reason for all this cause i know for sure the deathlord is gonna be spearheading all the stuff going down and it will probably be the most darkest if not the darkest time for the planet itself lol.
